Nintendo has added the Octo Expansion to Nintendo Switch Online Expansion Pack. If you have it you should definetely play Octo Expansion. It's a great game and I enjoyed it more than Splatoon 2's single player mode.

[ephemera-noctourniquet]

This expansion is the single greatest thing I have ever played. No other single player game has brought me such an immense amount of enjoyment while also providing intricate and fascinating lore, alongside an incredible OST to accompany it all.

If I had to bring a game to a deserted island, I'd bring this.

Can we just acknowledge how Agent 8 did all of this in high heels?

[christopherkidwell]

You don't even want to know how long it took me in that first flying level to figure out that you could cancel the flight by turning into an octopus.

*Pale summer moonlight shimmers on the seafloor.
An octopus, unaware that dawn will bring capture, Rests within a trap, dreaming fleeting dreams…*

i remember convincing my mom to buy this for me in 2019 and i’m still so obsessed with it

[keynanmartinez]

Probably One Of The Best Video Game DLC's Ever Made Plus The Aesthetic And Tone Reminds Me Of "Akira".

Funny how all the boss stations are places where lines intersect. I wonder if that was intentional on Nintendo's part.
Edit: FINE I added the Promised Land bosses, are you happy now?

[brianmillar]

Thank you so much! the one where you have to match the shape KILLED me thank you so much for doing this walkthrough!

[heavenharmonyyy]

fun fact about co2 (line c) when you first spawn in go to the first enemy but you dont have to shoot you can actually walk up to the enemy until they fall of the cliff BUT BE SURE TO DODGE THE FIRST ENEMY"S ATTACK WHEN ITS BACKING UP FROM U

ive played every splatoon game since 2015, obiv i grew out of it since splatoon 3 sadly but i still come back every month to check up on newer stuff. THIS GAME HAD A GRIP ON ME AND WAS MY ENTIRE LIFE, even my dad played it and he is still sad about splatoon 1 because that was his favorite part. this dlc and side order were the best purchases of my life. to the plot, ost, and charaters are amazing and ill never find a game that i will enjoy more then splatoon in gen

[Biver.is.a.silly.billy]

No ones acknowledging that pearl and captin cuttlefish were rap battling

[LineOfThy]

tartar doing slang talk is the best thing ever

[Borntobeheaded-zp]

When I first got this I LOVED IT and now hearing Captain cuttlefish’s theme gives me goosebumps 🐙🐙🐙

5:11:55 That song was stuck in my head during summer 2019

[splatoonafish]

I just got this game 2 weeks ago off of an Amazon sale. Than the other day after the splat 3 news I find out after already contemplating buying the octo expansion, that it comes for free for those who have expansion pack. Last 2 days have gone directly to playing this expansion. I just got my octoling to the surface like 2 hours ago lol. What a great time.

[Biancalovestosew]

5:03:28 and 7:43 That sound was stuck in my head all day idk why.

[chocolaanimuevaxx]

The fact that this exact game was made astounds me. It is absolute perfection.

[AyanaProdan]

Agent 8 is so cool. And she have lots and lots of talents! She's my favourite a
agent!

[AzerBlu]

Thank you so much for this!! Now I don't have to buy a whole game and a dlc for it just to get to see the lore of Octo Expansion.
